Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.
Research on guinea pig embryos uncovers similarities to human embryogenesis, advancing understanding of preimplantation stages and reproductive techniques.
Scientists at Oak Ridge National Laboratory have developed a first-ever method of detecting ribonucleic acid, or RNA, inside plant cells using a technique that results in a visible fluorescent signal.
A new study from the Hebrew University of Jerusalem reveals that bacterial movement plays a central role in the transfer of antibiotic resistance genes. The research team discovered that the rotation of flagella in Bacillus subtilis acts as a mechanical signal that activates key conjugation genes.
A team of researchers led by Dr. Kim V. Narry, director of the Center for RNA Research at the Institute for Basic Science (IBS), has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics.
A study conducted by researchers at Oregon Health & Science University has revealed a novel mechanism by which proteins can be modified within cells. This finding may have significant implications for the understanding of immune system functionality.
Life emerged on Earth some 3.8 billion years ago. The "primordial soup theory" proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously formed organic molecules.
Ever wondered what happens to your body when you take those trendy ice baths? Scientists at the University of Ottawa just found out, and it's pretty fascinating.
Researchers at the Francis Crick Institute have found that the small intestine grows in response to pregnancy in mice. This partially irreversible change may help mice support a pregnancy and prepare for a second.
In a recent study, scientists have developed a revolutionary chromosome identification system for alfalfa, one of the world's most economically vital forage crops.
Humans are not the only species that may assist their injured companions; mice might exhibit similar behaviors, as demonstrated by a recent study conducted by researchers at the Keck School of Medicine of USC and published in Science.
A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a "ball-and-chain" channel-plugging mechanism, according to investigators at Weill Cornell Medicine.
Published in Nature Machine Intelligence, an Australian team led by Monash University researchers has developed a generative AI tool that mimics scientists to support and speed up the process of scientific discoveries.
Previously, researchers thought that microRNA was a kind of useless residue in cells and blood. But these tiny threads are far more important than some imagined. Also for those who study wildlife.
A new study has revealed the clearest-ever picture of the surface chemistry of worm species that provides groundbreaking insights into how animals interact with their environment and each other.
Physical activity is not only important for fitness, but also for health. This is confirmed by a new study conducted under the direction of Prof. Dr. Maximilian Kleinert at the German Institute of Human Nutrition Potsdam-Rehbrücke (DIfE). His team discovered that the protein PanK4 plays a crucial role in the energy metabolism of skeletal muscles.
Lemons owe their signature tang to citric acid, yet the molecular mechanisms governing its accumulation have long remained a mystery.
AIST researchers, in collaboration with JAMSTEC, Hokkaido University and Tohoku University, have succeeded in cultivating an ultrasmall bacterial strain parasitizing archaea and classified the strain PMX.108T as new species and genus of Minisyncoccus archaeiphilus.
Our guts are home to trillions of bacteria, and research over the last few decades has established how essential they are to our physiology – in health and disease.
As many as 40% of Americans are obese, putting them at an increased risk for high blood pressure, diabetes, stroke, heart disease and certain cancers, according to the CDC.
Nerve cells use incredible energy-saving techniques while still carrying out their primary functions.
